顶管施工减少了大量前期工作,包括建筑物拆迁及围护、公用管线搬迁等问题。特别是可以在不中断行车的情况下穿越铁路施工,是近年来发展非常迅速的施工方法。通过以钢筋砼套管顶管工程为例,介绍顶管施工的主要工作流程方案,并简要分析顶管施工过程中的偏差原因和常用的纠偏措施,以期对类似顶管工程施工起到一定的指导作用。
Pipe jacking has reduced a great deal of previous work, including demolition and house demolition and relocation of public pipelines. In particular, it is possible to cross the railway without interrupting the traffic and is a very rapid construction method developed in recent years. By taking reinforced concrete casing pipe jacking project as an example, the main work flow scheme of pipe jacking construction is introduced, and the causes of deviation and common corrective measures in pipe jacking construction are briefly analyzed in the hope of achieving a certain level of similar jacking construction Guidance.
